Woman politician allegedly attacked by Bajrang Dal activists

Jan 1: Two army personnel were killed in a gunfight with heavily-armed Pakistani infiltrators along the Line of Control (LoC) in Jammu and Kashmir's Rajouri district on Wednesday, officials said.

The infiltrators were intercepted in the Khari Thrayat forest when they were trying to sneak into India from Pakistan-occupied Kashmir (PoK), they said.

"Two army soldiers martyred during cordon and search operation in Nowshera sector. The operation is still in progress and further details are awaited," Jammu-based Indian Army Public Relations Officer (PRO) Lt Col Devender Anand said in a statement.

The search operation was launched following information about the movement of suspected terrorists, the officials said.

The infiltrators opened fire on the troops and during a fierce gunfight, the two soldiers were killed, they said.

The officials said a massive operation is on in the area.

Kashmir, Mar 3: Four days after the National Investigation Agency made a major breakthrough in the Pulwama terror attack case over a year after the bombing, arresting one person who had sheltered the suicide bomber Adil Ahmad Dar, the NIA on Tuesday arrested two more people in the case - a father-daughter duo - who had also provided shelter to the bomber, officials said.

The NIA also claimed that the video of the suicide bomber was also recorded at their residence and released by the Jaish-e-Mohammad (JeM) terror group from Pakistan after the attack. An NIA spokesperson in Delhi said: "Two more persons have been arrested by the agency in the Pulwama terror attack case and they have been identified as Insha Jan, 23, and her father Tariq Ahmed Shah, 50, who works as a tipper driver."

The official said that the father-daughter duo have been arrested from Hakripora area in Pulwama for their involvement in the attack. The two were arrested on early Tuesday morning after senior officials of the NIA raided their house on Monday night.

A senior NIA official related to the probe told IANS: "The video of Dar, who attacked the CRPF convoy, was recorded at the home of the duo. And the same video was released soon after the Pulwama terror attack by the JeM terrorists from a Pakistani IP address."

He said, "The video was shared by them to their handlers in Pakistan."

The spokesperson further claimed that during the probe Tariq Ahmed Shah disclosed that his house in Hakripora area was used by Dar, Mohammad Umar Farooq, a Pakistani terrorist and IED maker, Kamran - another Pakistani terrorist (both were later killed in encounters with security forces), Sameer Ahmed Dar, a Jaish-e-Mohammad terrorist from Pulwama and Mohammad Ismail aka Ibrahim, a Pakistani terrorist.

The spokesperson said that Shah facilitated all the terrorists at his house for sheltering and for planning of the heinous attack on the CRPF convoy. He said Jan, daughter of Shah, facilitated the terrorists at their home and provided food and other logistics during their stay on more than 15 occasions for two to four days each time, in their house during the year 2018-2019.

"Initial interrogation has revealed that Jan was in constant touch with Farooq and was in communication with him over telephone and other social media applications," the spokesperson said. The fresh arrests of the two accused brings the total number of arrests in the case to three.

The arrests were made on the revelations of Shakir Bashir Magrey, who was arrested by the anti-terror probe agency on February 28. According to senior NIA officials, more arrests will be made in the coming days. Magrey, a resident of Hajibal, Kakapora in Pulwama district of Jammu & Kashmir, is an overground worker (OGW) of the Pakistan-based Jaish-e-Mohammad (JeM).

According to agency sources, Magrey allegedly provided shelter and other logistical assistance to the Pulwama suicide bomber. He was sent to 15 days' NIA custody by a special NIA court in Jammu & Kashmir on Friday. During interrogation, Magrey revealed that he had harboured Dar and Pakistan-based terrorist Mohammad Umar Farooq in his house from late 2018 till the attack in February 2019 and assisted them in the preparation of the Improvised Explosive Device (IED). His shop is located near Lethpora bridge, and as advised by Mohammad Umar, he started conducting reconnaissance of the movement of CRPF convoys on Jammu-Srinagar Highway in January 2019, and informed Mohammad Umar and Adil Ahmad Dar about it.

Magrey was also involved in modifying the Maruti Eeco car and fitting the IED into it in early February, 2019 and was introduced to Adil Ahmad Dar in mid-2018 by Mohammad Umar and he became a full-time OGW of JeM.

"During his initial interrogation, he disclosed that on several occasions, he collected and delivered arms, ammunition, cash and explosive material to JeM terrorists, including those involved in the Pulwama attack," the agency had said on February 28.

"During investigation, the make, model and number of the car used in the attack was quickly ascertained by NIA to be a Maruti Eeco through forensic examination of the tiny remnants of the car which were found at the spot during extended searches," the agency stated.

"This has been corroborated by accused Shakir Bashir Magrey. The explosives used in the attack were determined to be ammonium nitrate, nitro-glycerin and RDX, through forensic investigation," it said.

The coronavirus can stay aloft for hours in tiny droplets in stagnant air, infecting people as they inhale, mounting scientific evidence suggests.

This risk is highest in crowded indoor spaces with poor ventilation, and may help explain superspreading events reported in meatpacking plants, churches and restaurants.

It’s unclear how often the virus is spread via these tiny droplets, or aerosols, compared with larger droplets that are expelled when a sick person coughs or sneezes, or transmitted through contact with contaminated surfaces, said Linsey Marr, an aerosol expert at Virginia Tech.

Aerosols are released even when a person without symptoms exhales, talks or sings, according to Marr and more than 200 other experts, who have outlined the evidence in an open letter to the World Health Organization.

What is clear, they said, is that people should consider minimizing time indoors with people outside their families. Schools, nursing homes and businesses should consider adding powerful new air filters and ultraviolet lights that can kill airborne viruses.

What does it mean for a virus to be airborne?

For a virus to be airborne means that it can be carried through the air in a viable form. For most pathogens, this is a yes-no scenario. HIV, too delicate to survive outside the body, is not airborne. Measles is airborne, and dangerously so: It can survive in the air for up to two hours.

For the coronavirus, the definition has been more complicated. Experts agree that the virus does not travel long distances or remain viable outdoors. But evidence suggests it can traverse the length of a room and, in one set of experimental conditions, remain viable for perhaps three hours.

How are aerosols different from droplets?

Aerosols are droplets, droplets are aerosols — they do not differ except in size. Scientists sometimes refer to droplets fewer than 5 microns in diameter as aerosols. (By comparison, a red blood cell is about 5 microns in diameter; a human hair is about 50 microns wide.)

From the start of the pandemic, the WHO and other public health organizations have focused on the virus’s ability to spread through large droplets that are expelled when a symptomatic person coughs or sneezes.

These droplets are heavy, relatively speaking, and fall quickly to the floor or onto a surface that others might touch. This is why public health agencies have recommended maintaining a distance of at least 6 feet from others, and frequent hand washing.

But some experts have said for months that infected people also are releasing aerosols when they cough and sneeze. More important, they expel aerosols even when they breathe, talk or sing, especially with some exertion.

Scientists know now that people can spread the virus even in the absence of symptoms — without coughing or sneezing — and aerosols might explain that phenomenon.

Because aerosols are smaller, they contain much less virus than droplets do. But because they are lighter, they can linger in the air for hours, especially in the absence of fresh air. In a crowded indoor space, a single infected person can release enough aerosolized virus over time to infect many people, perhaps seeding a superspreader event.

For droplets to be responsible for that kind of spread, a single person would have to be within a few feet of all the other people, or to have contaminated an object that everyone else touched. All that seems unlikely to many experts: “I have to do too many mental gymnastics to explain those other routes of transmission compared to aerosol transmission, which is much simpler,” Marr said.

Can I stop worrying about physical distancing and washing my hands?

Physical distancing is still very important. The closer you are to an infected person, the more aerosols and droplets you may be exposed to. Washing your hands often is still a good idea.

What’s new is that those two things may not be enough. “We should be placing as much emphasis on masks and ventilation as we do with hand washing,” Marr said. “As far as we can tell, this is equally important, if not more important.”

Should I begin wearing a hospital-grade mask indoors? And how long is too long to stay indoors?

Health care workers may all need to wear N95 masks, which filter out most aerosols. At the moment, they are advised to do so only when engaged in certain medical procedures that are thought to produce aerosols.

For the rest of us, cloth face masks will still greatly reduce risk, as long as most people wear them. At home, when you’re with your own family or with roommates you know to be careful, masks are still not necessary. But it is a good idea to wear them in other indoor spaces, experts said.

As for how long is safe, that is frustratingly tough to answer. A lot depends on whether the room is too crowded to allow for a safe distance from others and whether there is fresh air circulating through the room.

What does airborne transmission mean for reopening schools and colleges?

This is a matter of intense debate. Many schools are poorly ventilated and are too poorly funded to invest in new filtration systems. “There is a huge vulnerability to infection transmission via aerosols in schools,” said Don Milton, an aerosol expert at the University of Maryland.

Most children younger than 12 seem to have only mild symptoms, if any, so elementary schools may get by. “So far, we don’t have evidence that elementary schools will be a problem, but the upper grades, I think, would be more likely to be a problem,” Milton said.

College dorms and classrooms are also cause for concern.

Milton said the government should think of long-term solutions for these problems. Having public schools closed “clogs up the whole economy, and it’s a major vulnerability,” he said.

“Until we understand how this is part of our national defense, and fund it appropriately, we’re going to remain extremely vulnerable to these kinds of biological threats.”

What are some things I can do to minimize the risks?

Do as much as you can outdoors. Despite the many photos of people at beaches, even a somewhat crowded beach, especially on a breezy day, is likely to be safer than a pub or an indoor restaurant with recycled air.

But even outdoors, wear a mask if you are likely to be close to others for an extended period.

When indoors, one simple thing people can do is to “open their windows and doors whenever possible,” Marr said. You can also upgrade the filters in your home air-conditioning systems, or adjust the settings to use more outdoor air rather than recirculated air.

Public buildings and businesses may want to invest in air purifiers and ultraviolet lights that can kill the virus. Despite their reputation, elevators may not be a big risk, Milton said, compared with public bathrooms or offices with stagnant air where you may spend a long time.

If none of those things are possible, try to minimize the time you spend in an indoor space, especially without a mask. The longer you spend inside, the greater the dose of virus you might inhale.
